A look at three players you should know and three others who will need to come through for each team.
YOU SHOULD KNOW
Clinton McDonald, defensive tackle
The Broncos use at least three wide receivers 90% of the time. That means Seattle's nickel defense will be on the field most of the time. McDonald anchors the middle of that front as the nickel nose tackle.
Byron Maxwell, cornerback
Considering how much Peyton Manning throws the ball, the Seahawks need a solid corner opposite All-Pro Richard Sherman. Maxwell showed his value after Brandon Browner was hurt and Walter Thurmond was suspended.
Michael Robinson, fullback
This game will be about playing keep-away from Manning, and that means the Seahawks controlling the clock. Robinson is the blocking back who helps open holes for Marshawn Lynch, getting him to linebacker level.
WHO MUST COME THROUGH
Russell Wilson, quarterback
Wilson is incredibly elusive, and he can make plays with his feet as well as his arm. He can also get into trouble by scrambling too much. Can he maintain his composure on the biggest stage of his life?
Marshawn Lynch, running back
The centerpiece of Seattle's offense, "Beast Mode" generally needs to be gang tackled. He has had back-to-back 100-yard games in the playoffs, and he wears defenses down, often breaking big runs in the fourth quarter.
Richard Sherman, cornerback
A confident trash talker, Sherman is also among the best defensive playmakers in the league. His pass breakup that clinched a trip to the Super Bowl exemplified his incredible length and athleticism.
YOU SHOULD KNOW
Trindon Holliday, receiver/returner
